为了充分发挥夏播大豆石豆4号的增产潜力，以石豆4号为试材，采用二因素（播期和密度）三水平（播期6月15日、6月25日和7月5日，密度18．0万株／hm2、22．5万株／hm2和27．0万株／hm2）完全随机区组试验设计，分析了不同播期和密度处理对大豆主要农艺性状及产量的影响，并筛选出该品种高产栽培的适宜播期与密度组合。结果表明：播期对大豆生长发育和产量的影响大于密度，在一定播期范围内密度对大豆生长发育和产量影响不显著；适宜石豆4号高产的播期与密度组合为播种期6月15日、种植密度18．0万～27．0万株／hm2，其中播种期为6月15日、种植密度为27．0万株／hm2时产量最高。

In order to give full play to yield potential of the summer sowing soybean Shidou No.4, completely randomized design was executed with two factors (sowing period and density) and three levels (sowing period of June 15, June 25 and July 5, density of 18.0 ×104 plants/hm2, 22.5 ×104 plants/hm2 and 27.0 ×104 plants/hm2), which analyzed the influence on agronomic characters and yield of Shidou No .4 with different sowing periodsand densities, and the suitable combination of sowing period and density for high -yield cultivation was selected.The results indicated that sowing period had higher impact on the growth , development and yield of soybeanthan that of density, and in a certain range of sowing period, density had no significant effect on growth and yield of soybean. The suitable combination of sowing period and density for high-yield cultivation of Shidou No.4was sowing period of June 15 and density of 18.0 ×104 -27.0 ×104 plants/hm2, and the highest production was achieved under the sowing period of June 15 and density of 27.0 ×104 plants/hm2.
